METALLIC SHEATHING.

Original application filed April 6, 1911,

' To all whom t may concern:

Be it known that l, HENRY S. HALE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented. certain new and useful Improvements in Metallic Sheathing, of which the following is a specication. V y,

rll`his invention is directed to the provision of an' improved form of sheathing made of usenrsa sheathing for the exterior and interior surfaces of the` side walls of railway cars and other structures, and improved means for securing the sheathing in position.

This application is a division of my application entitled metallic sheathin Serial No. 619,213., filed April 6, 1911, in W icih certain forms of-securing devices are claimed.

In the present application another form of securing devices for the sheathing will be claimed characterized by the use of coacting flanged securing devices'on the supporting structure and the sheathing together with a strip or strips or wedge pieces inserted within the inner flanges of the coacting devices to spread the same into firm engagement with the outer fianges of the coacting de VlCeS- rll`he objects of the invention are accordingly to provide a sheathing which can be readilyy manufactured and applied to a wall at low cost, together with means for quickly and eiiiciently mounting the same in position, in the manner referred to, and so that if one piece of sheathing ,becomes damaged,

it may be removed and another inserted in its place.

1n accordance with the invention the sheathing consists of a number of sections suflicient to fill thedesired space, each of these sections preferably being formed from a piece of sheet-.metal of substantial size pressed to provide therein a plurality of ribs extending parallel to each other and serving to strengthen the sheet so as to prevent distortion thereof, these ribs preferably extending inwardly. These sheets are secured to the wall by means of coacting securing devices in the manner referred to, these securing devices being such 'Specification of Letters Patent.

Serial No. 619,213. Divided and this application led February 10,1915. Seria1No.7,249.

as to lpermit the several plates of the sheathing to be slid into position by` a lateral movement thereof and then firmly held in position by the wedge pieces or strlps referred to. Preferably the engaglng surfaces of the securing devices are of comparatively small area so that the area of the metallic'path through the wall of a car is small and therefore the passage o-f heat through the wall is considerably reduced.

my invention may be had, attention is here- In order that a clearer understanding 'of l by directed to the accompanying drawingsl .forming part of this application and illustrating certain forms of my invention.

lln the drawings, Figure l is a partial vertical sectional view of the sheathing mounted in position, Fig. 2 is an elevation thereof, Fig. 3 is a horizontal section of the sheathing mounted in position, and Fig. 4f is y an enlarged vertical section illustrating the securing devices.

Referring to these drawings, the sheath-.

ing consists of a plurality of plates of sheet-r metal o-f substantial size, each of the same preferably being pressed so as to provide therein a plurality of parallel ribs integral with the plate upon the inner side thereof. One of these plates is indicated at 1 and the ribs are shown at 2. In forming these ribs the metal of the plate is pressed inwardly and then the side walls of this inwardly extending portion are brought together so as to lie side by side as shown in Fig. 3. These ribs serve to stiffen the plate to the lower edge of the wall and the other near the upper edge thereof, one only of these rails bein shown in the drawings. 1f the wall is of su stantal height, one or more CII additional rails 4 may be provided between the upper and lower ones. The rails 4 are irovided with curved flanges .5 as shown, anges 5 extending outwardly from the wall.

Upon the inner sides of each of the plates 1 are mounted a plurality of securing devices 6 in position to coiiet with the rails el, these securing devices lying between the adjacent ribs 2 of the sheathing and being secured to the plates 1 in any suitable manner lint preferably by welding them thereto. The securing devices (l are formed of sheetmetal pieces and have their liiteral edges outwardly turned from the body portions thereof as shown at 7 and flanges 8 are provided upon the ends of these outwardly extending portions, the fliinges 8 enacting with the flanges 5 of the i'ails 4 to secure the sheathing to the Wall 3. Preferably the securing devices 6 are tempered so as to give them a good spring action, the flanges 8 being arranged to enter between the flanges 5 on rails 4. In mounting the plates 1 of the sheathing in iosition, the flanges 8 may be engaged within the flanges 5 and the plate 1 moved relatively until it reaches a desired position. After one ormore of the plates of the sheathing have been properly ositioned, strips or wedge pieces 9 may be inserted between the flanges -of the securing pieces (l so as to spread the flanges 8 thereof and hold them in firm engagement with the flanges 5 on rails 4. This engagement of the strip or strips 9 with the coactiiig flanges ensures a firm engagement of the sheathing and prevents any rattling which might otherwise take place. The form of the s ring metal securing devices also permits tie sheet 1 to be positioned by moving it bodily toward the wall, the flanges 7 of the securing devices 6 being moved inwardly until the same have passed within the flanges 5 of rails 4, when the sheathing is in proper position, whereupon the flanges of the securing devices will spring into position within flanges 5 after which the wedge pieces 9 may be inserted in position.

Another advantage of the construction herein described is that the sheathing is spaced apart slightly from the wall and the metallic parts connecting the sheathing plates and the wiill are of comparatively small cross-section, as a result of which the transmission of heat through the metal of the wall takes place to only a slight extent, and the spaces between the sheathing and the wall form dead-air spaces through which heat is transmitted but poorly.

I Wish it to be understood that my invention is not limited strictly to the exact construction illustrated in the drawings, but that it includes reasonable equivalents therefor, and generally speaking, is as broad as is indicated by the accompanying claims.

Ilaviiig described my invention what I claim as new therein and desire to secure by Letters .latent of the lliiited States is:

1. In sheathing construction, the combination of a supporting structure, a pair of rails secured thereto, having flanges, a sheet-metal sheathing, and a plurality of swing-metal securing devices fixed to said sheathing at distributed points along lines corresponding to said rails, said securing devices having flanges thereon courting with the flanges on the rails to secure the sheathing in position, With the flanges of one of euch pair of coacting members within the flanges of the other, and strips positioned between the inner flanges of each pair to spread the latter into firm engagement with the outer flanges, substantially as set forth.

2. In sheathing construction, the combination of asupporting structure` a rail secured thereto having flanges, a sheet-metal sheathing consisting of a slieet-inetal plate having a plurality of integral parallel ribs therein su istantially perpendicular to the general plane of the sheathing and on the inner side thereof, and a plurality of spring metal securing devices fixed to said sheathing at distributed poiiits along lines corresponding to said rail between said ribs, said securing devices having flanges thereon coacting with the flanges on the rails to secure the sheathing in position with the flanges of one of each pair of coacting members within the flanges of the other and strips positioned between tlie inner flanges of each pair to spread the latter into firm engagement with the outer flanges. substantially as set forth.

3. In sheathing construction, the combination of a supporting structure` a sheet-metal sheathing, and coactiiig flanged securing devices comprising elements fixed to said structure and sheathing respectively, one of which comprises a flanged rail and the other a group of coactiiig flanged devices, one element of said devices heilig of slieet-metal, and the flanges of said element being inserted within the flanges of the other, to secure the sheathing in position, said coacting devices being in line, and a strip positioned within the inner flanges of the coacting devices to spread the same into firm engagement withthe other flanges, siibstantially as set forth.

This specification signed and witnessed this 8th day of February. 1915.
